Description
The Si9241EY is a monolithic bus transceiver designed to
provide bidirectional serial communication in automotive
diagnostic applications.
The device incorporates protection against overvoltages
and short circuits to GND or V
protected and can be driven beyond the V
A fault output provides an active low in case of a short
circuit or an open load. In the event of an over temperature
condition, the output is immediately switched off and a fault
indicated. This condition can only be reset once the over
temperature condition is removed, and CS is toggled high.

For bi-directional communication, CS must be High for
“receive” and Low for “transmit”. If CS is Low, while IC
is receiving data, an incorrect fault signal will occur. To
inhibit the open load and short detect, tie CS and T
together.
The Si9241EY is built on the Siliconix BiC/DMOS
process. An epitaxial layer prevents latchup.
The RX output is capable of driving CMOS or
